RESUMO

Trichothiodystrophy, also called sulphur-deficient brittle hair syndrome, is a rare autosomal recessive genetic disorder of DNA repair and transcription. Trichothiodysthrophy is characterised by dry, thin, easily broken hair, showing alternating light and dark pattern called 'tiger tail' banding under polarizing light microscopy. According to our knowledge, our report is the first one on this rare disorder from Hungary: a case of a 9-year-old boy showing clinical features typical of trichotiodystrophy. Sequence analysis of the ERCC2 gene identified two recurrent trichothidodystrophy missense heterozygous mutations - c.934G/A p.Asp312Asn (CM015299) and c.2251A/C p.Lys751Gln (CM004814) - suggesting compound heterozygous state of the patient and confirming the clinically suspected diagnosis of trichothiodystrophy.

RESUMO

BACKGROUND: Post-transplant anaemia (PTA) is common and is associated with adverse consequences. The protein-energy wasting (PEW) syndrome is associated with erythropoietin resistance in patients on maintenance dialysis. We assessed the association between PEW and PTA in a large prevalent cohort of stable kidney-transplanted patients. METHODS: Data from 942 prevalent kidney-transplanted patients were analysed. Socio-demographic parameters, laboratory results, transplantation-related data and medication were obtained from the charts. Biomarkers reflecting nutritional status and inflammation [serum leptin, albumin, interleukin-6 (IL-6), tumour necrosis factor-α (TNF-α) and C-reactive protein] were measured. Anthropometric measures and the malnutrition-inflammation score (MIS) were also tabulated. Anaemia was defined according to the guidelines of the American Society of Transplantation. RESULTS: Mean age was 51 ± 13 years, 57% were males and 22% had diabetes. The prevalence of PTA was 33%. The haemoglobin (Hb) level significantly and negatively correlated with the MIS (rho = - 0.316), marginally with serum TNF-α (rho = - 0.079) and serum IL-6 (rho = - 0.075) and positively with serum transferrin (r = 0.298), serum albumin (r = 0.274), abdominal circumference (r = 0.254) and serum leptin (rho = - 0.152), P < 0.05 for all. In a multivariable linear regression model, MIS was independently associated with Hb (beta = - 0.118, P = 0.004) in patients with estimated glomerular filtration rate (eGFR) lower than or equal to 60 mL/min/1.73 m(2), but not in patients with higher eGFR. CONCLUSIONS: The MIS is independently associated with PTA in the kidney-transplanted population with eGFR lower than or equal to 60 mL/min/1.73 m(2).

RESUMO

BACKGROUND: Chronic protein-energy wasting, termed malnutrition-inflammation complex syndrome, is frequent in patients with chronic kidney disease and is associated with anemia, morbidity, and mortality in patients on maintenance dialysis therapy. The Malnutrition-Inflammation Score (MIS) recently has been developed and validated in dialysis patients. STUDY DESIGN: Observational cross-sectional study. SETTING & PARTICIPANTS: 993 prevalent kidney transplant recipients. PREDICTOR: MIS computed from change in body weight, dietary intake, gastrointestinal symptoms, functional capacity, comorbid conditions, decreased fat store/Systemic Global Assessment, signs of muscle wasting/Systemic Global Assessment, body mass index, serum albumin level, and serum transferrin level. OUTCOMES: Markers of inflammation and malnutrition, including serum C-reactive protein, interleukin 6, tumor necrosis factor alpha, serum leptin, prealbumin, body mass index, and abdominal circumference. The relationship was modeled by using structural equation models. RESULTS: Mean age was 51 +/- 13 years, 57% were men, and 21% had diabetes. Median time from transplant was 72 months. MIS significantly correlated with abdominal circumference (r = -0.144), serum C-reactive protein level (r = 0.094), serum interleukin 6 level (r = 0.231), and serum tumor necrosis factor alpha level (r = 0.102; P < 0.01 for all). A structural equation model with 2 latent variables (malnutrition and inflammation factor) showed good fit to the observed data. LIMITATIONS: Single-center study, lack of information about vascular access, presence of nonfunctioning kidney transplant, relatively high refusal rate. CONCLUSIONS: Our results confirm that MIS reflects both energy-protein wasting and inflammation in kidney transplant recipients. This simple instrument appears to be a useful tool to assess the presence of protein-energy wasting in this patient population.
